Emission Spectra Gas Samples https://physicsfunshop.com/search?keywords=emission A favorite demonstration in my collection- where pure samples of hydrogen, nitrogen and five noble gasses are subjected to the high frequency pulsed field of a miniature Tesla coil. Each gas has a characteristic breakdown voltage and emission spectrum- note that Nitrogen has the highest breakdown voltage and begins to glow after the presence of my hand temporarily lowers the resistance to current flow for that tube.

Vintage Bulb Spectra: emission line spectra identify the gas within these two vintage discharge glow bulbs- revealed here by a 500 line/mm diffraction grating. The color of each gas is due to a mix of the colors emitted from electron energy transitions specific to each element, the basis of spectroscopy. ➡️ Follow the link in my profile for info on where to get a diffraction grating slide and many other amazing items featured here on @physicsfun #physics #physicstoy #physicsfun #neon #argon #emi
